Detect Low-Level Microbial Contamination

Bacteria present in water samples cause issues such as
biofilm formation (biofouling) and microbially induced corrosion (MIC). Traditional
testing methods such as heterotrophic plate count (HPC) requires days of
culturing bacteria. By the time you find out there’s contamination, it’s
already too late. The Water-Glo™ System is based on ATP bioluminescence
technology, allowing consistent low-level detection of all live microbes in
minutes instead of days. It’s the ideal early warning system to protect your
process.

Protect Your Process With Water-Glo

Detect all viable microbes present:

No bias from composition of growth media, as seen with plate counting.

Get results in minutes:

No need to wait for microbes to grow in media to obtain assay results.

Monitor Low Levels for Sensitive Applications

Frequently Asked Questions

What is ATP and how can you use it to measure bacteria?

ATP is the "energy currency" of all living cells and degrades rapidly when a cell dies. Because of this property, ATP serves as a biomarker for living organisms in a sample and can be used to quantitate the live microbes present.

What is bioluminescence?

Many living organisms, including fireflies, release light energy from chemical reactions. These reactions are catalyzed by proteins in the cell called luciferases, and they require oxygen, ATP and a luciferase substrate. The bioluminescent reaction can be harnessed to detect the required components (such as ATP) in the environment.

How does ATP measurement compare to other forms of microbial detection?

Most common methods for detecting microbes in water measure biofouling potential (TDC, AOC or BDOC) or the development of biofouling (pressure drop or BFR). Heterotrophic plate counting directly measures viable microbes, but it is slow and detects less than 10% of viable bacteria. Flow cytometry and PCR improve turnaround time and accuracy but neither method directly measures live bacteria. ATP detection is the only method that directly assesses living cells from any type of microbe, providing an immediate indication of microbial contamination in your sample.

Will the Water-Glo™ Kit identify what kind of contaminants are in my sample?

No. The Water-Glo™ Kit detects the presence of living organisms, but does not identify the species. It can be used as an early detection system, and if a bioluminescent signal is detected, other methods, such as PCR or NGS, may be used to identify the specific organism.
